$primary_id_field is the primary key of your table (in our case categoria_id)$table_name is the name of our table (in our case vnt_categorie)$parent_field is the parent field name for example parent_id (in our case the name is parent_id)$title_field is the title field that you want to appear from the table (in our case categoria)$title_display_as the string that it will show for example to select the categories (in our case 'Select Categoria' )$where is the where field . It works like the where of the set_relation. You can simply add it as a null if you don't want to add.
